Abstract: With the worldwide rapid increase of demand for aerospace applications, such as aircraft, spaceflight missions, and construction of space stations, aluminium alloy integral panels were designed and manufactured to decrease the cost and improve their performance. This review paper briefly introduces the applications, material selection, and development of manufactural technologies of the aluminium alloy integral panels. The manufactural technologies of the integral panels involved milling machining, press bending forming, extrusion, shot peening, creep age forming (CAF), and spin forming. Some developing shot peening and CAF technologies greatly supported a balance among cost, weight, and performance of the aluminium alloy integral panels, which avoided excessive manual labour, low material efficiency, and a mass of machining. The challenge of the combination of structural design, materials selection, and manufactural technology to improve the balance among cost, weight, and performance of the integral panels requires further research and development.
